Abstract (en)

In processes for the hydrolysis of alkylene oxide to form alkyene glycols in the presence of selectivity-enhancing organometalate wherein the organometalate is provided in a water-insoluble phase, a stabilizing material is used to enhance the stability of the organometalate. The stabilizing material is water-soluble and comprises a cation and a selectivity-enhancing metalate anion.
